boot disk. A SCSI disk that contains the
Windows operating system. For the Endurance
server, the boot disk for the CE is a member of a
mirrored disk set that physically resides on the
IOPs. The boot disk for an IOP is non-mirrored
and local to that IOP.
booting. A process for a system that includes
passing POST and loading a system’s Windows
operating system.
callout. The selection by Endurance’s fault
handling software of a specific component as
being responsible for a failure.
CE.
Compute Element. In an Endurance server,
the system that provides all compute processing
for the server. The CE runs the operating system
where you install and execute all Endurance server
applications.
CE boot disk.
The mirrored SCSI disk that the
CE uses as its boot device. The CE boot disk is
physically located in the IOPs. It contains the CE’s
copy of Windows and Endurance software. By
default, the boot disk is the mirrored SCSI disk
with the lowest SCSI address among redirected
disks.
CE Desktop application. A standard
Windows graphical user interface (GUI)
application that runs on the IOPs and displays CE

constant computing. A process that
automatically deconfigures a failed component
and continues processing with its redundant
counterpart. This process helps ensure no loss of
service. However, if a non-mirrored device is
failed out of an Endurance configuration, it has no
counterpart to provide continuous device access.
disable. Manually remove a component from
the active Endurance configuration. Components
are disabled using an Endurance Manager or
MTCCONS command.
disabled. A state indicating that an Endurance
